Refresh page within an iframe
提问by DarthVader
I have an app (facebook canvas app, facebook displays the app in an iframe)
我有一个应用程序(facebook 画布应用程序,facebook 在 iframe 中显示该应用程序)
When the user clicks on a link I want to be able to refresh the page.
当用户单击链接时,我希望能够刷新页面。
the code i m using to refresh the page is as follows:
我用来刷新页面的代码如下:
window.location.reload(true);
With firefox this works fine, it only refreshes the current page within the iframe. So i m happy.
使用 Firefox 可以正常工作,它只会刷新 iframe 中的当前页面。所以我很高兴。
With IE, the whole page is being refreshed which causes the user to go the beginning of the app.
使用 IE,整个页面都会被刷新,这会导致用户进入应用程序的开头。
How can i avoid that?
我怎样才能避免这种情况?
I just want refresh the current page not the current url.
我只想刷新当前页面而不是当前 url。
apps.facebook.com/foo/
is the app URL and within URL user clicks on a link go to a page, then within that Page i need to refresh that page to update some counters. but when i refresh the whole request goes to apps.facebook.com/foo/
是应用程序 URL,在 URL 中,用户点击链接转到页面,然后在该页面内,我需要刷新该页面以更新一些计数器。但是当我刷新整个请求时apps.facebook.com/foo/
any ideas?
有任何想法吗?

<div id="wrapper"></div>

Javascript
function reload () {
var fr=document.getElementById('tehframe');
if(fr!=null) document.getElementById("wrapper").removeChild(fr);
var iframehtml="<iframe id='tehframe' src=…></iframe>";
document.getElementById("wrapper").innerHTML=iframehtml;
}
Then just call reload()
at the beginning and whenever you want to load it.
然后只需reload()
在开始时调用,只要你想加载它。

You can change the url of the iframe and cause a refresh by adding a meaningless parameter to the url eg foo becomes foo?bar
您可以更改 iframe 的 url 并通过向 url 添加一个无意义的参数来引起刷新,例如 foo 变为 foo?bar
